VEIW OF A NON-BIOLOGIST (but knew some chemistry once):
You better start with the Avogadro #, chemical composition of a cell
(I guess, the average atomic weight is about 12 as we are mostly
a mixture of H, O, C amd N) and average size of a cell, which
(again a guess) is about several microns.
The answer has nothing to do with the weight of human body
and likely about the same for all (animal) biostuff.
